A microsatellite study to disentangle the ambiguity of linguistic, geographic, ethnic and genetic influences on tribes of India to get a better clarity of the antiquity and peopling of South Asia
An understanding of the genetic affinity and the past history of the tribal populations of India requires the untangling of the confounding influences of language, ethnicity, and geography on the extant diverse tribes. The present study examines the genetic relationship of linguistically (Dravidian, Austro‐Asiatic, and Tibeto‐Burman) and ethnically (Australian and East Asian) diverse tribal populations (46) inhabiting different regions of the Ind…
Genetic Affinity Between Diverse Ethnoreligious Communities of Tamil Nadu, India
Historically, a number of local Hindu caste groups have converted to Islam and formed religious endogamous groups. Therefore the local caste groups and religious communities in a region are expected to show genetic relatedness. In this study we investigate the genetic relationship between Tamil-speaking (Dravidian language) Muslims (Sunni), six endogamous Hindu castes, and a tribal ethnic group (Irulars) using 13 CODIS (Combined DNA Index System)…
Intertribal and Temporal Allele-Frequency Variation at the ABO Locus Among Tibeto-Burman-Speaking Adi Subtribes of Arunachal Pradesh, India
We studied the distribution of ABO blood group frequencies of the Galo and Mishing subtribes of the Adi tribal cluster in East Siang District, Arunachal Pradesh, India, in order to investigate the intertribal and temporal allelic variation. Blood groups O and AB showed higher frequencies (28.4%, 27.4%) in the Galo, whereas group O (45%) was predominant in the Mishing. Allele r is significantly different in the Galo (44.6%) and Mishing (60.3%). Th…
Genetic Kinship Among an Isolated Adi Tribe of Arunachal Pradesh
Isolated tribes in remote areas are important for genetic studies, and one such little known subtribe of the Adi tribe, namely, the Adi Panggi (Pangi) of the Upper Siang District of Arunachal Pradesh, India, was studied for surname distribution to deduce the deviation from random mating and genetic kinship between villages. The estimates of homonymy (homozygosity) vary between villages; husbands show wider variation (0.009 to 0.23) than wives (0.…
Antiquity, geographic contiguity and genetic affinity among Tibeto-Burman populations of India
Overall, geographic contiguity, punctuated by isolating barriers, is a major influencing factor of genetic affinity among the TB population; contiguous populations within a region show greater genetic relationship than with distant TB populations over a wide geographical area. The results of the microsatellite study also support the history of diverse routes of migration of these populations
Microsatellite diversity reveals the interplay of language and geography in shaping genetic differentiation of diverse Proto‐Australoid populations of west‐central India
Microsatellite diversity was analyzed in four Proto‐Australoid tribes, including Indo‐European (Marathi)‐speaking Katkari, Pawara, Mahadeo‐Koli, and Dravidian (Gondi)‐speaking groups of Maharashtra, west‐central India, to understand their genetic structure and to identify the congruence between language and gene pool. Allele frequency data at 15 short tandem repeat (STR) loci in studied tribes was compared with data of 22 Indo‐European‐ and Dravi…
Genetic Heterogeneity Among Three Adi Tribes of Arunachal Pradesh, India
We studied the distribution of ABO blood groups among three little known subtribes of the Adi tribe, namely, the Panggi, Komkar, and Padam, of the East and Upper Siang districts of Arunachal Pradesh, India. Blood group O was the predominant group in the Komkar and Padam, whereas group A was the predominant group in the Panggi. Blood group AB was found to be the least frequent group in all three studied populations. The populations showed signific…
Spatial patterns of anthropometric variation in India with reference to geographic, climatic, ethnic and linguistic backgrounds
The results suggest geographical clines for the four anthropometric variables and indicate the influence of population structure on the studied variables
Genetic structure and affinity among eight ethnic populations of Eastern India
The nature and extent of genetic variation at 22 polymorphic DNA loci, belonging to three distinct classes, especially, 12 STR loci (D3S1358, vWA, FGA, D5S818, D13S317, D7S820, D8S1179, D21S11, D18S51, HPRTB, F13B, LPL), four VNTR loci (D1S7, D4S139, D5S110, D17S79), and six coding loci (HLDQA1, LDLR, GYPA, HBGG, D7S8, GC) were investigated among eight population groups of West Bengal and Manipur regions of India. Of these, two groups from West B…
Geographic contiguity and genetic affinity among five ethnic populations of Manipur, India
The results reinforce that using both VNTR and STR loci in detecting regional genetic affinity among the populations is more effective than using VNTR or STR independently, and also confirm the results obtained from the serological and electrophoretic data. However, the clustering pattern obtained from combined DNA markers is more in conformity with the pattern obtained by STR loci rather than with VNTR loci. Despite linguistic, geographical and …
Climate and head form in India
The relationship between head form and climatic variation was investigated in different tribal and caste populations of India. The magnitude of the cephalic index varies significantly in different zones. In tropical zones, head form is longer (dolicocephalic), but in temperate zones, head form is more round (mesocephalic or brachycephalic), especially among Scheduled Tribes (ST) and Scheduled Castes (SC) than among other castes. These trends poss…
Anthropometric variationin the Yanadi
Anthropometric variation and sex differences were investigated among the Yanadi tribe, who live in different regions and show differences in population structure variables and form regional breeding populations. In case of within population variation in anthropometric characters, both males and females show greater variation in a few specific characters (e.g., HB, LL) and almost no variation in FB, but least variation in HL and NB in males and in…
The method of pattern combination analysis in dermatoglyphics
A method of pattern combination analysis (PCA) is described. It consists of three categories: Pattern combination types (PCT), Triradial pattern combination types (PCT-tr) and Pattern combination ratios (PCR) with specific reference to ten digits and its several indices. The method has been used to investigate its validity in discriminating subdivided populations among the Yanadi tribe. The results show significant differences and a few unique pa…
Possible paleopathological evidence of treponematosis from a megalithic site at Agripalle, India
An Iron Age (megalithic) skull recovered from a cist burial complex at Agripalle, Andhra Pradesh, India, exhibits extensive erosion of the calvarium, areas of sclerotic diploe, irregular osteitic and periosteitic lesions, and deep ulcerations with a granulomatous appearance of nodular foci due to bone remodeling. These lesions are found over the entire surface, but are less severe in the temporal region and in the occipital region below lambda. T…
Genetic structure of a tribal population
Microevolutionary changes in morphology were investigated in a transient tribal population who are fast changing from a hunting-gathering to an agricultural stage. Anthropometric data on 14 measurements collected from the Yanadi, who inhabit different geographical regions and differ in their subsistence and other associated cultural traits, demonstrate high morphologic differentiation between two levels of organization: (1) 12 settlements and (2)…

Dermatoglyphic study among sex and other crime convicts
An attempt was made to investigate dermatoglyphic variation between four sex-crimes (SC) and four sex and other crime (SOC) convicts. These were compared with 10 endogamous and 11 penal populations. The results indicate that the two closely related sex crime cases IPC-363 and IPC 366 («kidnap» and «abducting») show wide differences in dermatoglyphic characters. A comparison of sex crimes with sex and other crime cases showed least differences in …
Size and shape components of anthropometric differences among the Yanadis
Size and shape components of Mahalanobis D2 were computed from a set of anthropometric characters among the Yanadis, a tribe in the south eastern part of Andhra Pradesh, India. These people are in a transitional stage of development and show differences in sociocultural variables between different geographical regions. From the study it appears that the pattern of differences due to size and shape is the same as that of general distance, irrespec…
Genetic structure of a tribal population
Extent of breeding isolation was estimated by two different sources among the Yanadi tribe, who inhabit different geographical regions and show wide cultural differences. The estimate based on marriage frequency shows the formation of more or less well defined regional breeding populations, whereas the estimate based on surname frequency indicates past migration, gene flow and common affinity between regional populations. Both the sources consist…
Ecological Theory and Ethnic Differentiation Among Human Populations [and Comments and Replies]
The formation and maintenance of distinct ethnic populations within multiethnic communities is proposed to be functionally equivalent to the process of species diversification in multispecies communities. This paper suggests that while these processes operate through different selective mechanisms-one social and the other genetic-ethnic boundaries, like species boundaries, function to regulate the behavior of potentially competing populations in …
